The SR22 is a fully assembled and certified four seater. This is an experimental kit two seater that you have to assemble at least 51% yourself, so it's not really comparable. The base SR22 also has a more expensive electronics package from what I can tell.

The more expensive "ready to fly" kit is more comparable to a Cessna 172 in price, though with more than double the range. But you still have to assemble most of it yourself, the "Ready to fly" version isn't actually ready to fly.
